The stats aggregation returns the count, sum, min, max, and average all at once.

```sql SQL
SELECT pdb.agg('{"stats": {"field": "rating"}}') FROM mock_items
WHERE id @@@ pdb.all();

```python Django
from paradedb import Agg, All, ParadeDB

MockItem.objects.filter(
    id=ParadeDB(All())
).aggregate(agg=Agg('{"stats": {"field": "rating"}}'))
```

```ruby Rails
MockItem.search(:id)
        .match_all
        .facets_agg(agg: ParadeDB::Aggregations.stats(:rating))
```
